Which type of medication can be obtained without a prescription?

Over-the-counter medications are formulated and marketed for use without a prescription. They are generally considered safe for use by the public when used as directed. These medications are typically used to treat common and minor health issues, such as headaches, colds, or allergies, making them easily accessible for individuals without needing to consult a healthcare professional.

In contrast, controlled substances require strict regulation and are often prescribed due to their potential for abuse or dependency. Prescription drugs necessitate a healthcare provider's oversight to ensure they are used safely and effectively for specific medical conditions. Specialty medications are often complex therapies for chronic or rare conditions and also require a prescription due to the specialized nature of their use and monitoring. Therefore, over-the-counter medications stand out as the only class among the options that can be purchased without a prescription, allowing for greater ease of access for consumers.
